"I'm so grateful for the fun times, the knowledge, the friendships, the love, the family that we have created together," Aduba chimed in, as Manning called the show "an amazing journey" and "an amazing experience."

Before sighing off, Uzo also promised that fans "will not be disappointed" by the episodes still to come.

"It is a season you will not forget," she said. "And we're going to give you everything and more than you could have ever wanted. Thank you, thank you, thank you."
